...China triumphantly announced that they had found the reason. Tang's favorite wife, they alleged, had been kidnapped from Jehol and was being held in Peiping, a hostage of his loyalty, by China's "Young Marshal" Chang Hsuehliang. Setting out from Peiping, U. S. newshawks bumped 100 mi. over awful roads from Peiping to Tang's Capital, Chengteh...
...England's late (1850-1925) Oliver Heaviside, bookstore keeper who for amusement invented mathematical forms to describe the behavior of alternating currents. Radio waves are presumed to reflect from the Layer much as light beams reflect from a mirror. Estimates place the Layer at 50 to 250 mi. from Earth's surface and picture it as roughly spherical.* At night the Layer shrinks comparatively close to Earth; by day, as the Sun puts in its effect, it recedes. But this theory of diurnal, tide-like pulsation has not explained all radio reactions against the Kennelly-Heaviside Layer...
...state-owned railways, canals and skidways over the Alleghenies, built to compete with New York's booming Erie Canal. Canal boats, constructed in sections, were trundled through the streets of Philadelphia on low-wheel trucks, hauled to a railway, then chuffed, towed, pushed and slid over the 395 mi. of "State Works" to Pittsburgh. In winter when canals froze, all transportation ceased. It was a thoroughly unsatisfactory procedure, so a group of Philadelphians built the Pennsy...
...trains faster-the Soviet budget having no particular balancing point.* Though critics insist that U. S. railroads have been technological laggards (compared to other U. S. industries), the fact remains that the U. S. railroad plant is the finest in the world. Of the world's 780,000 mi. of railways about one-third is in the U. S. Some say that the plant is too big, that the $26,000,000,000 it cost was too much, that the peak of its usefulness has passed. The reason it is in quicksand is not that its trains...
...third day the flyers picked up the coastline, had only to follow it as far as they could: Fuel ran low, so they landed at Walfish ("Whalefish") Bay, 770 mi., short of Cape Town. Total distance: 5,340 mi., a non-stop distance record. Flying time...
